What does it mean to be a sheltered city?

Asylum cities refer to those cities that do not enforce federal immigration laws, including San Francisco, San Jose, Oakland, Seattle, new york and Chicago. Nowadays, more and more immigrants will seek asylum at the border, and the Department of Homeland Security in the United States has formulated new rules, which have raised the standards for the formal application for entry of protectors. If the applicant submits sufficient evidence to prove that he is most likely to be persecuted, he can approve the asylum application. The applicant's fear must also be at least one of the five principles stipulated by law. If a person can persuade the Immigration Bureau to restore his original nationality, he is likely to be persecuted for reasons consistent with the above five principles. There is a good chance that he will grant political asylum. A city that can provide political asylum for these immigrants is called a asylum city.
